A blue light flashed, and doctors rushed to the aid of CNN's Larry King, who was in the same hospital room where President Reagan was taken after he had been shot six years earlier.

King was having a massive heart attack. That was 20 years ago. "So this is an issue near and dear to my still-beating heart," King said to an audience of about 350 people Friday at the Ronald Reagan Presidential Library and Museum.

King, along with former first lady Nancy Reagan and several heart-health advocates, were there to open the First Ladies Red Dress Collection, spotlighting gowns and suits worn by the seven living first ladies while they were in the White House. more
